Interactive Query and Search in Semistructured Databases [chapter]

Roy Goldman, Jennifer Widom
1999 Lecture Notes in Computer Science  
In this paper we propose a new model for interactively querying and searching semistructured databases.  ...  We demonstrate the importance of efficient keyword search, structural summaries of query results, and support for inverse pointers.  ...  Implementation Status Our interactive query and search model, along with the necessary supporting features discussed in this paper, are under development within the Lore project.  ...

Interactive Query Formulation in Semistructured Databases [chapter]

Agathoniki Trigoni
2002 Lecture Notes in Computer Science  
In this paper, we propose an interactive and adaptive framework that guides the user in the search for data, by disclosing only a part of the underlying information at a time.  ...  The idea behind this paper is that the tradeoff between allowing natural queries and receiving quality (complete and accurate) results, could be compromised if we adopted an interactive and adaptive query  ...  Conclusion In this paper, we proposed an interactive and adaptive model for querying semistructured databases.  ...

Content-based lecture access for distance learning

Guang-Ho Cha, Chin-Wan Chung
2001 IEEE International Conference on Multimedia and Expo, 2001. ICME 2001.  
The structural summaries are useful for browsing and querying the database, building indexes, and enabling query optimization; (3) Index structures to speed up the search to find appropriate lecture contents  ...  Education and training are expected to change dramatically due to the combined impact of the Internet, database, and multimedia technologies.  ...  In irregular semistructured database, without schema, it is difficult to query and browse the database, to construct indexes, and to perform query optimization.  ...

Graphical representation of RDF queries

Andreas Harth, Sebastian Ryszard Kruk, Stefan Decker
2006 Proceedings of the 15th international conference on World Wide Web - WWW '06  
In this poster we discuss a graphical notation for representing queries for semistructured data.  ...  We try to strike a balance between expressiveness of the query language and simplicity and understandability of the graphical notation. We present the primitives of the notation by means of examples.  ...  We plan to include in the system client-side scripts to be able to interactively compose queries within a Web browser. Definition 1 ( 1 RDF Facet).  ...

Searching the Deep Web, the huge diversity of databases behind Web portals and query forms, requires mappings between (mostly schemaless) queries and record structures of potential target databases [13  ...  IR systems understand queries as approximate, best-effort formulations of the user's information needs, and then aim to support an interactive process of data exploration, query rephrasing, and guidance  ...

A Content-Oriented Data Model for Semistructured Data

Tomas Novotny
2007 Databases, Texts, Specifications, Objects  
The ECMAScript object model is widely used to manipulate data in web applications. However, none of these models is intended to be used directly in an interactive way.  ...  There are several data models that are capable of handling semistructured data. The best known are OEM, XML DOM, RDF, and the ECMAScript object model. All these models have different purpose.  ...  I would like to express many thanks to Christoph Quix, who has taught me to write a paper and with whom I was consulting the content of this paper, and Roger Hughes, who made a deep language correction  ...

2005 Proceedings of the 2005 ACM SIGMOD international conference on Management of data - SIGMOD '05  
We have developed a generalpurpose tool that offers users helpful navigation and refinement options for seeking information in these semistructured repositories.  ...  With the growing importance of systems containing arbitrary semistructured relationships, the need for supporting users searching in such repositories has grown.  ...  Randall Davis, and Suelene Chu for help with the content of this paper.  ...

Relevancy in schema agnostic environment

Muhammad Ali Norozi
2012 Bulletin of IEEE Technical Committee on Digital Libraries  
This work is about exploring relevancy in semi-structured retrieval both in isolation and as bridge between database and information retrieval communities.  ...  Relevance is an important component in full-text search and often distinguishes the implementations. Relevancy is used to score matching documents and rank them according to the users intent.  ...  . database records) and semistructured data (e.g.  ...

Type inference for queries on semistructured data

Tova Milo, Dan Suciu
1999 Proceedings of the eighteenth ACM SIGMOD-SIGACT-SIGART symposium on Principles of database systems - PODS '99  
We study the problem of type checking and type inference for queries over semistructured data.  ...  Introducing a novel traces technique, we show that the problem is difficult in general (NP-complete), but can be solved in PTIME for many practical cases, including, in particular, queries over XML data  ...  In this paper we study the interaction between schemas and queries in semistructured data.  ...
